and short-wave infrared wavelengths were selected and harmonized at a spatial resolution of 250-meters3. A flood detection algorithm relying on the reflectance values from these bands used a threshold approach to classify each pixel as water or not water in every MODIS image over the relevant wa...
watersheds with higher percentage of area with agricultural land cover were more likely than otherwise comparable watersheds to contain a city with an IWS program. Watersheds with lower percentage of area protected were also more likely to contain a city with ...

Eutrophication of freshwater systems can result in blooms of phytoplankton, in many cases cyanobacteria. This can lead to shifts in structure and functions of phytoplankton communities adversely affecting the quality of drinking water sources, which in turn impairs public health. Relationships between stru...
The major computational challenge for developing LSH datasets is processing gridded meteorological and attributes data. To make the development and augmentation of Caravan as democratic as possible (i.e., to make it as easy as possible for anyone to add new watersheds or new data layers to the...
As a result, many forested wetlands are now subject to a combination of direct precipitation and backwater flooding as the major sources of hydrology (Smith Fig. 1 Theoretical hydropatterns for an alluvial swamp forest (upper panel) and hardwood wetland forest (middle panel; adapted from Mitsch ...
water. Even trees with large water use and storage capacities would have limited impacts on watershed hydrology if they cover a relatively small area of land. Thus, hydrologic models representing watersheds or landscapes that contain tree species that can alter water balance may overestimate water ...
Satellite imagery from MODIS, operated by NASA and available since 2000, was acquired for dates and watersheds identified as a flood event in the DFO catalog3. MODIS is fre- quently used to map inundation62–64 and provides two satellite images per day with global coverage. We analyzed ...
2002). The detention of precipitation in forested wetlands has the capacity to alter the timing, extent, and magnitude of downstream flooding within watersheds, even in systems not directly influenced by flooding (Acreman and Holden 2013). For example, mature forested wetland evapotranspiration has ...
California has seen a recent increase in wildfire frequency and magnitude, which has led to large tracts of burned areas within the watersheds of many reservoirs. A need exists to understand the transport and fate of LWD standing and on the ground from the burned sub watersheds to reservoirs ...
