چکیده
Abstract Tuntang watershed is one of the national priority watersheds in Jratunseluna river basin that has a big potential for water availability. The development strategic area causes changes land cover which can result reduced catchment areas. purpose this study was to simulate effect change on annual discharge trends and analyze balance projection based change. This uses data 2019 Kedungsepur National Strategic Area (KSN) plan. Daily rainfall 11 years from 2010 2020 obtained through Global Precipitation Measurement (GPM) satellite validated using 7 rain stations located watershed. Meanwhile, evapotranspiration Land Data Assimilation System. In addition, Digital Elevation Model (DEM), flow accumulation, direction HydroSHEDS are used provide information surface shape Then been as input simulation spatial hydrological model determine Rainfall-runoff-inundation (RRI) model. an years. Furthermore, comparison made between rate map with KSN development. Based result, it known there absorption region KSN, resulted increased extreme trend region.

Detecting and Modelling the Trend of Change in the Forest Land Use in Garasu Watershed Area Using Landscape Metrics
Detecting, predicting and quantifying the trends of landscape pattern change in the forests of Gharasu watershed area are necessary so as to assess the crises or prevent them. To this aim, the land use maps belonging to the years 1987, 2002 and 2018 were classified through the maximum likelihood method, and the forest area changes were estimated. Then, through the Geomod model and the forest ch...

Climate variability and change is threatening water resources around the world. One hundred and fourtheen (114) stations from Reference Hydrometric Basin Network (RHBN) around Canada with at least 30 years continuous data (up to 2011) were selected to study the trend in mean annual runoff for different periods of 30 to 100 years in step 10 years by non-parametric Mann-Kendall test. Effect of sh...
