it is still under investigation on how to improve the TGD's ability to mitigate the damages of extreme weather events, such as severe droughts and floods. As a prerequisite to answer these questions, the characteristics of the spatial and temporal distribution patterns of land surface parameters at regional scales instead of local scales need to be evaluated. In this study, we focused on the land surface soil moisture, which is one of the most important parameters for the studies of global and

this study is to illustrate how urbanization in an impounded watershed can affect flood generation into an artificial reservoir. To achieve this, hypothetical but realistic future land-use and land-cover scenarios are considered for ARW. First, the actual LULC was used to simulate floods with actual observed precipitation storms and PMP. Here urbanization is represented in a form of impervious area that affects only infiltration rate and soil moisture recharge. It is clear urbanization does not

author) at CBRFC, a regional operational center supplying short- and seasonal-range model-based streamflow forecasts to SLC water operations and management, facilitated the application of existing calibrated hydrology models for the SLC system. CBRFC's modeling environment includes the Sacramento Soil Moisture Accounting Model (SACSMA) coupled with the Snow-17 temperature index snow model ( Burnash 1995 ; Burnash et al. 1973 ; Anderson 1973 ). These models (referred to in aggregate as “the CBRFC

module involves calculation of an index of catchment storage s t , based upon an exponentially decreasing weighting of precipitation and temperature conditions, with where s t is the catchment storage index or catchment wetness/soil moisture index at time t , generally varying from 0 to 1; τ w ( T t ) is a time constant that is inversely related to the temperature declining rate; τ 0 is the value of τ w ( T t ) for a reference temperature fixed to a nominal value depending on the climate and
