TL;DR: The development and the application of ArcCN-Runoff tool, an extension of ESRI@ ArcGIS software, which can be applied to determine curve numbers and to calculate runoff or infiltration for a rainfall event in a watershed are reported.

TL;DR: In this paper, the authors demonstrate the robustness of the steady shape concept for inversion of hydraulic tomography data and investigate its robustness with respect to improperly specified boundary conditions.

TL;DR: In this article, a multisite investigation assessed the major controls on diurnal water table fluctuations and the eco-hydrologic insights that can be gleaned from them, and found that spatial and temporal variations in the amplitude of the fluctuations are primarily a function of variations in meteorological drivers of plant water use, vegetation density, type, and vitality.

TL;DR: In this paper, a field-scale assessment of hydraulic tomography in a porous aquifer, with an emphasis on the steady shape analysis methodology, is presented, and the hydraulic conductivity (K) estimates from steady shape and transient analyses of the tomographic data compare well with those from a tracer test and direct-push permeameter tests, providing a field validation of the method.

TL;DR: In this article, a semianalytical solution is presented for a mathematical model describing the flow of groundwater in response to a slug or pumping test in a highly permeable, confined aquifer.
