Abstract The Kissimmee River Basin (Florida, USA) underwent river channelization in the 1960s and subsequent restoration 1990s, revealing a shift management emphasis from flood protection to wetland health. In this paper, is hypothesized result changing human values preferences, power differential between more numerous affluent upstream urban residents (who prioritize restoration) downstream rural protection). We develop conceptual sociohydrologic model simulate interactions community...

Abstract Stylized sociohydrological models have mainly used social memory aspects such as community awareness or sensitivity to connect hydrologic change and response. However, alone does not satisfactorily capture the details of how human behavior is translated into collective action for water resources governance. Nor it only mechanism by which two‐way feedbacks sociohydrology can be operationalized. This study contributes toward bridging this gap developing a model flood resilience that...

Man-made reservoirs are key components of terrestrial hydrological systems. Identifying the location and number is premise for studying impact human activities on water resources environmental changes. While complete bottom-up censuses can provide a comprehensive view reservoir landscape, they time-consuming laborious thus infeasible global scale. Moreover, it challenging to distinguish man-made from natural lakes in remote sensing images. This study proposes convolutional neural network...

Surface soil moisture (SM) plays an essential role in the water and energy balance between land surface atmosphere. Low spatio-temporal resolution, about 25–40 km 2–3 days, of commonly used global microwave SM products limits their application at regional scales. In this study, we developed algorithm to improve resolution using multi-source remote sensing data a machine-learning model named General Regression Neural Network (GRNN). First, six high spatial input variables, including Land...

The Earth's water cycle involves energy exchange and mass movement in the hydrosphere thus sustains dynamic balance of global hydrologic cycle. All variables on Earth are closely interconnected with each other through process circulation. Observing, understanding predicting storage, movement, quality remains a grand challenge for contemporary science technology, especially researches across different spatio-temporal scales. remote sensing observing platform has unique advantage acquiring...

Surface soil moisture is a key variable in the exchange of water and energy between land surface atmosphere, critical to meteorology, hydrology, ecology. The Tibetan Plateau (TP), known as "The third pole world" "Asia's towers", exerts huge influences on sensitive global climates. In this situation, longer time series can provide sufficient information understand role TP. This paper presents first comprehensive dataset (2002-2015) spatio-temporal continuous at 0.25° resolution, based...

Extensive studies have highlighted the roles of rainfall, impervious surfaces, and drainage systems in urban pluvial flooding, whereas topographic control has received limited attention. This study proposes a depression-based index, Topographic Control Index (TCI), to quantify function topography flooding. The TCI depression is derived within its catchment, multiplying catchment area with slope, then dividing by ponding volume depression. A case demonstrated Guangzhou, China, using 0.5...

Temporally continuous daily actual evapotranspiration (ET) data play a critical role in water resource management arid areas. As typical remotely sensed land surface temperature (LST)-based ET model, the temperature-vegetation index (Ts-VI) triangle model provides direct monitoring of ET, but these estimates are temporally discontinuous due to cloud contamination. In this work, we present gap-filling algorithm (TSVI_DNN) using deep neural network (DNN) with Ts-VI obtain at regional scale....

Land-surface temperature (LST) plays a key role in the physical processes of surface energy and water balance from local through global scales. The widely used one kilometre resolution daily Moderate Resolution Imaging Spectroradiometer (MODIS) LST product has missing values due to influence clouds. Therefore, large number clear-sky reconstruction methods have been developed obtain spatially continuous datasets. However, is theoretical value that often an overestimate real value. In fact,...

Despite the well-known design principles of vascular systems, it is unclear whether arterial tree obeys some scaling constraints during normal growth and ageing in a given species. Based on micro-computed tomography measurements coronary trees mice at different ages (one week to more than eight months), we show constant exponent 3/4, but age-dependent coefficients length–volume law ( L c crown length, V volume, K coefficient) ageing. The 3/4 represents self-similar fractal-like branching...
