TL;DR: In this article, field measurements and numerical simulations are used to assess the resons for different types of water-related structural damage observed in Tacloban and Eastern Samar during Typhoon Yolanda.
Abstract: Field measurements and numerical simulations are used to assess the resons for different types of water-related structural damage observed in Tacloban and Eastern Samar. Coastal Tacloban saw heavy damage due to wind waves riding atop storm surge, while inland Tacloban experienced much lighter damage because wind waves were not present (though inundation by surge soiled structures). Eastern Samar experienced little wind-induced or pressure-induced setup, but breaking-wave-induced setup over the reef combined with wave runup and infragravity motions caused heavy damage along the coast.

TL;DR: In this article, a field survey in the affected area elucidated the critical breaking conditions of Japanese coastal pine trees and identified the regions of large-tree debris production, where most broken trees remained in the vegetated region, but scoured regions behind the sea wall or on the down slope regions of sand dunes produced large pieces of tree debris.
Abstract: Coastal vegetation is widely recognized to reduce tsunami damage, but coastal forests in large areas of the Tohoku and Kanto districts of Japan were destroyed by the tsunami after the Great East Japan Earthquake on 11 March 2011. A field survey in the affected area elucidated the critical breaking conditions of Japanese coastal pine trees and identified the regions of large-tree debris production. Most broken trees remained in the vegetated region, but scoured regions behind the sea wall or on the down-slope regions of sand dunes produced large pieces of tree debris. In contrast, the pine trees in the inland zone were found to trap much debris. This trapping function should be utilized more in future designs. A numerical model that includes the breaking phenomena of trees estimates the capacity of a coastal forest to reduce the washout region of houses by around 150 m. This is not a negligible component of the mitigation measures when a large tsunami occurs and overflows the sea embankment.

TL;DR: In this paper, satellite-based rainfall data GSMaP_MVK+ with gauge observed rainfall over the Nepal Himalayas was verified at two levels, firstly for the whole country and secondly for physiographic regions.
Abstract: This paper verifies satellite-based rainfall data GSMaP_MVK+ with gauge observed rainfall over the Nepal Himalayas. Assessment of the accuracy is done at two levels, firstly for the whole country and secondly for physiographic regions. Verification of daily rainfall at a country level shows that the GSMaP_MVK+ captures the spatial distribution of rainfall well but underestimates with a correlation coefficient 0.79, bias -2.6 and RMSE 4.8 mm day-1 and percentage error of -55%. Verification with physiographic regions show that the GSMaP_MVK+ performs well in flatter terrain with a correlation coefficient of higher than 0.8 and prediction accuracy of 70%; however, performance deteriorates with increase in altitude. In the Mid and High Mountain areas the correlation coefficient is 0.4 with prediction of 40% or less. The results indicate the need for improvement of GSMaP_MVK+ estimates by considering orography in the algorithm or bias adjustment before application in the Himalayas.

TL;DR: In this article, the authors investigated potential impacts of land use and land cover change on water budget of the Chi river basin in Thailand, including an conversion of forested area, expansion of farmland, switching of rice paddy fields to energy crops and two scenarios involving conversion of farmland to rice and sugarcane plantations.
Abstract: Land use and land cover (LULC) have been continuously changing, through human activities, leading to variations in hydrological cycle. In this study, we applied SWAT model to investigate potential impacts of LULC on water budget of the Chi river basin in Thailand. Five plausible scenarios of land use change were evaluated, including an conversion of forested area, expansion of farmland, switching of rice paddy fields to energy crops and two scenarios involving conversion of farmland to rice and sugarcane plantation. The results indicated that different land use scenarios contributed to various effects in annual and seasonal water yield and evapotranspiration (ET). Conversion of forested area and farmland showed slightly small changes on water flows and ET. Substitution of paddy fields by sugarcane plantation showed clearly reduced water flows and increased ET by almost 5.0% in dry season. Particularly, in case of expansion of rice paddy fields to farmland, small changes occur on annual flow and ET but more significant effect occur on seasonal flows. The results showed decrease in ET by nearly 12.0%, leading to increase of water yield by up to 5.1% during dry season. Finally, conversion of farmland to sugarcane plantation for biofuel production showed significant effect on seasonal ET, mainly decreasing in dry season by 4.5 % but small changes were detected on water yields.
