Abstract For numerous hydrological applications, information on snow water equivalent (SWE) and liquid content (LWC) are fundamental. In situ data much needed for the validation of model remote sensing products; however, they often scarce, invasive, expensive, or labor‐intense. We developed a novel nondestructive approach based Global Positioning System (GPS) signals to derive SWE, height (HS), LWC simultaneously using one sensor setup only. installed two low‐cost GPS sensors at high‐alpine...
Abstract. Water supply of most lowland cultures heavily depends on rain and melt water from the upstream mountains. Especially melt-water release alpine mountain ranges is usually attributed a pivotal role for large downstream regions. scarcity assumed as consequence glacier shrinkage possible disappearance due to global climate change (GCC), in particular parts Central Southeast Asia. In this paper, application validation coupled modeling approach with regional model (RCM) outputs...
The amount of liquid water in snow characterizes the wetness a snowpack. Its temporal evolution plays an important role for wet-snow avalanche prediction, as well onset meltwater release and availability estimations within river basin. However, it is still challenge not yet satisfyingly solved issue to measure content (LWC) with conventional situ remote sensing techniques. We propose new approach based on attenuation microwave radiation L-band emitted by satellites Global Positioning System...
Snow water equivalent (SWE) is a key variable for various hydrological applications. It defined as the depth of that would result upon complete melting mass snow. However, until now, continuous measurements SWE are either scarce, expensive, labor-intense, or lack temporal spatial resolution especially in mountainous and remote regions. We derive dry-snow conditions using carrier phase from Global Navigation Satellite System (GNSS) receivers. Two static GNSS receivers used, whereby one...
Climate change has a large impact on water resources and thus hydropower. Hydroelectric power generation is closely linked to the regional hydrological situation of watershed reacts sensitively changes in quantity seasonality. The development hydroelectric Upper Danube basin was modelled for two future decades, namely 2021–2030 2051–2060, using special hydropower module coupled with physically-based model PROMET. To cover possible range uncertainties, 16 climate scenarios were taken as...
Abstract Monitoring seasonal snow cover properties is critical for properly managing natural hazards such as avalanches or snowmelt floods. However, measurements often cannot be conducted in difficult terrain lack the high temporal resolution needed to account rapid changes snowpack, e.g., liquid water content (LWC). To monitor essential snowpack properties, we installed an upward looking ground‐penetrating radar (upGPR) and a low‐cost GPS system below observed parallel its evolution during...
Soil moisture (SM) is a highly relevant variable for agriculture, the emergence of floods and key in global energy water cycle. In last years, several satellite missions have been launched especially to derive large-scale products SM dynamics on Earth. However, situ validation data are often scarce. We developed new method retrieve bare soil from measurements low-cost GPS (Global Positioning System) sensors that receive freely available L1-band signals. The experimental setup three was...
Abstract. Future climate change will affect the water availability in large areas. In order to derive appropriate adaptation strategies impact on balance has be determined a regional scale high spatial and temporal resolution. Within framework of BRAHMATWINN project model system DANUBIA, developed within GLOWA Danube (GLOWA Danube, 2010; Mauser Ludwig, 2002), was applied calculate components under past future conditions large-scale mountain watersheds Upper Brahmaputra. To use CLM output...
Battery storage systems can help to integrate excess Photovoltaic (PV) energy into the local but also increase request for higher self-consumption rates of households. This study uses a spatially resolved approach with hourly time steps analyze influence batteries on domestic residual loads regional scale. A component is developed consisting PV-system model, demand component, and battery device. The area located in south Bavaria 4906 households PV-systems between 3 10 kWp power were selected...
Abstract As the Intergovernmental Panel on Climate Change reported in 2013, climate change will have significant impacts all water sectors. Since is essential for live, culture, economy and ecosystems, adaptation crucial. Therefore, a legal political framework was established by commissions of European Union, United Nations national levels. For Danube River Basin (DRB), International Commission Protection got mandate to develop an strategy 2012 update this 2018. The natural science basis...
