The theory that forms the basis of Topmodel was first outlined by Mike Kirkby some 45 years
ago. This paper recalls some of the early developments; the rejection of the first journal …

In this synthesis paper addressing hydrologic scaling and similarity, we posit that roadblocks
in the search for universal laws of hydrology are hindered by our focus on computational …

The diversity in hydrologic models has historically led to great controversy on the correct
approach to process-based hydrologic modeling, with debates centered on the adequacy of …

This paper introduces Prec‐DWARF (Precipitation Downscaling With Adaptable Random
Forests), a novel machine‐learning based method for statistical downscaling of precipitation …

Soil moisture plays a key role in controlling land-atmosphere interactions, with implications
for water resources, agriculture, climate, and ecosystem dynamics. Although soil moisture …

After some background about what I have learned from a career in hydrological modelling, I
present some opinions about how we might make progress in improving hydrological …

Core Ideas Numerous studies have been conducted to develop and examine the accuracy
of the method. Cosmic‐ray neutron soil moisture estimates compare well with independent …

Abstract The National Weather Service (NWS) forecasts floods at approximately 3,600
locations across the United States (US). However, the river network, as defined by the 1 …

Land surface and hydrologic models (LSMs/HMs) are used at diverse spatial resolutions
ranging from catchment-scale (1–10 km) to global-scale (over 50 km) applications. Applying …

Accurate and detailed soil moisture information is essential for, among other things,
irrigation, drought and flood prediction, water resources management, and field-scale (ie …
