TL;DR: In this article, a model of parallel fractures, having equal spacing and width, has been applied to tracer movement in fissured rocks with a porous matrix, and the exact solution has been obtained for instantaneous injection.

TL;DR: In this article, the authors discuss the major advances in this subject and summarize the major direction of current studies, and discuss the effect of simplifications and assumptions on describing and understanding the phenomenon.

TL;DR: In this article, the rainwater interception storage capacities of mature canopy trees in a tropical rainforest site in northeast Queensland, Australia, were approximated using a combination of field and laboratory measurements.

TL;DR: In this article, a general hydrogeophysical model is outlined for aquifer-scale relations which are shown to depend primarily on two factors: the character of the material-level relationship; and the mutual relation between the direction of groundwater flow, aquifer layering, and Hydrogeophysical conditions in the aquifer.

TL;DR: In this article, the Gauss-Newton method for maximum likelihood (ML) parameter estimation of spatially correlated hydrologic fields is described with emphasis on computational aspects associated with its implementation.

TL;DR: In this article, the rates and mechanisms of local recharge in a semi-arid environment have been investigated beneath two major landscape settings in the Murray Basin in South Australia; these were calcrete flats with sinkholes and sand dunes in adjacent landscape settings.

TL;DR: In this article, the depth distributions of environmental chloride, deuterium and oxygen-18 in the deep sands (> 20 m) were monitored with a view to estimate average recharge to groundwater.

TL;DR: In this paper, the deuterium composition of Lake Frome has been used to make point estimates of evaporation from the floor of the normally "dry" lake frome, a salt lake in northern South Australia.

TL;DR: This analysis provides some interesting insights into the role that the quantity and quality of the data used play in the identification procedure in hydrologic model calibration and the precision of model parameter estimates.

TL;DR: In this article, the salinity reclamation study based on increased evaporation through the strategic use of trees is presented. But the work is limited to a small portion of the area in the south-west region of Australia, where the trees were in their seventh year after germination.

TL;DR: In this paper, an analytical relationship between modified transverse resistance and aquifer transmissivity has been developed for estimation from resistivity sounding data to optimize the information/cost ratio and avoid the indiscriminate and excessive use of drilling and pump testing.

TL;DR: In this paper, the authors measured the discharge-concentration relationship and the behaviour of the concentrations during storm events in two basins of the southwest of France: the Garonne (52,000 km2) and one of its tributaries, the Girou (520 km2).

TL;DR: In this article, the authors used the Rocky Mountain Arsenal near Denver, Colorado, U.S.A., as a realistic setting for a hypothetical test of a procedure that plans the hydraulic stabilization and removal of a groundwater contaminant plume.

TL;DR: In this article, the flow duration curve is regionalized by using morphoclimatic characteristics of the drainage basin, and the regionalized regression equations are successfully used to synthesize flow duration curves at other locations within the hydrologically homogeneous regions of western and northwestern Greece.

TL;DR: In this article, a general formula for the distribution of the annual maximum covering both the independent and dependent case has been derived, and the use of the formula has been exemplified.

TL;DR: In this article, the equations describing transport in fissured media, where transport in the matrix blocks is diffusive, are reduced to the standard form of a differential equation for the fissure phase.

TL;DR: The Chalk aquifer of eastern-central England is seriously affected by nitrates leached from agricultural land and, like many similar aquifers, its future as a potable resource must depend considerably on the nature and rates of denitrification as mentioned in this paper.

TL;DR: In this paper, the authors used geoelectrical depth soundings after Schlumberger were conducted over aquifers in glacial outwash deposits near a recessional moraine of Rhode Island in southern New England.

TL;DR: In this paper, a comparison between the analytical solution of the convection/diffusion equation in one dimension and a solution provided by the mixing-cell concept is made, and it is deduced that the latter describes transport of non-reactive and reactive components quite well, provided that certain conditions are met.

TL;DR: In this article, the exponential distribution is embedded in the generalized Pareto distribution (GPD) and the power of the finally proposed statistic (maximum/median) is compared with two other less simple statistics, one based on the behaviour of the ML estimator of the GPD-parameters and the other based on subsequent slopes in the probability plot.

TL;DR: VSAS2 as mentioned in this paper is a deterministic storm-flow simulator for small forested basins based on the variable source area concept, where the area of land yielding surface water to streamflow varies with time and that, for vegetated basins, subsurface flow not only sustains baseflow but is also a major component of storm flow.

TL;DR: A new algorithm is presented for quickly computing Thiessen weights for all stations in a collection network for each of several watersheds of interest, and substantial computational savings result by defining polygons by their edges instead of by their areal extent.

TL;DR: In this paper, a stream under thick snow cover in northern Hokkaido Island, Japan, was found to be 3° to 4°C during a snowmelt flood.

TL;DR: In this paper, the potentialities of remote sensing for partial-area hydrology are discussed for the various bands of the electromagnetic (E.M.) spectrum, and it is concluded that optimum use of the remotely sensed data requires a change in hydrological modelling, and appropriate adaption of models.

TL;DR: In this paper, the Institute of Hydrology Distributed Model is briefly described and its sensitivity to the parameters of the surface and subsurface flow components is examined for the Tanllwyth catchment, Powys, Wales.

TL;DR: In this article, a forest stream typical of those found in SE Belgium and NE France has been studied with respect to the parameters determining the dispersion of a non-reactive solute in a streamflow with stagnant zones.

TL;DR: In this paper, the analysis of results of experiments to find the diffusion coefficients and rock capacity factors for weakly-sorbed ions is discussed and improved agreement is obtained by using a new model in which the rock porosity is split into two parts: through-transport and dead-end pores.

TL;DR: In this paper, a series of equations were set up and solved using this concept and results for the most important diffusion parameters, namely: Di, the intrinsic diffusion coefficient, α, the rock capacity factor, and ψ, a pore geometry parameter which is a characteristic of the rock type in question.

TL;DR: In this article, the main physical phenomena related to the various types of runoff generation have been observed and analysed, including soil surface formations, texture and structure as well as vegetation cover, geological substrata, weathered material and climate.

TL;DR: In this paper, the amounts and time distribution of groundwater recharge from precipitation over an approximately 19-month period were investigated at two instrumented sites in south-central Kansas, and the authors found that Antecedent moisture conditions and the thickness and nature of the unsaturated zone were the major factors affecting recharge.
