Climatic variations caused by the excessive emission of greenhouse gases are likely to change the patterns of precipitation, runoff processes, and water storage of river basins. Various studies have been conducted based on precipitation outputs of the global scale climatic models under different emission scenarios. However, there is a limitation in regionaland local-scale hydrological analysis ...

Climate change in Northwest China could lead to the change of the hydrological cycle and water resources. This paper assessed the influence of climate change on runoff in the Manas River basin as follows. First, the temporal trends and abrupt change points of runoff, precipitation, and mean, lowest and highest temperature in yearly scale during the period of 1961–2015 were analyzed using the Ma...

As the frequency and magnitude of storm events increase with climate change, understanding how season management influence flood peaks is essential. The grasslands on peak timing was modelled for Swindale Calderdale, two catchments in northern England. Spatially-Distributed TOPMODEL used to investigate scenarios across four using empirically-based soil vegetation data. first scenario applied se...

The presence of ice in soil dramatically alters soil hydrologic and thermal properties. Despite this important role, many recent studies show that explicitly including the hydrologic effects of soil ice in land surface models degrades the simulation of runoff in cold regions. This paper addresses this dilemma by employing the Community Land Model version 2.0 (CLM2.0) developed at the National C...

A new procedure for the representation of flow directions and calculation of upslope areas using rectangular grid digital elevation models is presented. The procedure is based on representing flow direction as a single angle taken as the steepest downwards slope on the eight triangular facets centered at each grid point. Upslope area is then calculated by proportioning flow between two downslop...

Topographic indices like the Topographic Wetness Index (TWI) have been used to predict spatial patterns of average groundwater levels and to model the dynamics of the saturated zone during events (e.g., TOPMODEL). However, the assumptions underlying the use of the TWI in hydrological models, of which the most important is that groundwater level variation can be approximated by a series of stead...

The prediction of methane emissions from high-latitude wetlands is important given concerns about their sensitivity to a warming climate. As a basis for the prediction of wetland methane emissions at regional scales, we coupled the variable infiltration capacity macroscale hydrological model (VIC) with the biosphere–energy-transfer–hydrology terrestrial ecosystem model (BETHY) and a wetland met...

Abstract. Seasonal and interannual variations in global wetland area are a strong driver of fluctuations methane (CH4) emissions. Current maps extent vary their definition, causing substantial disagreement between large uncertainty estimates To reconcile these differences for large-scale CH4 modeling, we developed the Wetland Area Dynamics Methane Modeling (WAD2M) version 1.0 dataset at ? 25 km...

Restoration of eroded blanket peatlands through revegetation and gully blocking is observed to also deliver significant natural flood management (NFM) benefits (reduce delay floodpeaks). But there a lack clear understanding regarding how different catchment processes interact/counteract under each intervention scenario. We seek provide more insight by rigorously calibrating TOPMODEL rainfall-ru...

In 2015, the National Oceanic and Atmospheric Administration (NOAA) established Office of Water Prediction (OWP) in Weather Service (NWS). The mission OWP is to “collaboratively research, develop deliver timely consistent, state-of-the-science national hydrologic analyses, forecast information, data, guidance, decision-support services inform essential emergency management water resources decis...
