Too Hot, Too Cold, Just Right: Thermal Modulating Capacity of Different Sources of Groundwater Discharge to Salmon‐Bearing Streams

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Groundwater discharge plays a key role in maintaining habitat suitability for cold‐water fish by generating streamflow and modulating temperatures. However, the thermal influence depends on groundwater source depth and how far groundwater travels from the point of discharge to a receiving stream.

Combining Oral Histories and Participatory Mapping With Veteran Fishers to Identify Long‐Term Environmental Change in a Nationally Significant River

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT The detection and monitoring of environmental change is vital for sustainable river management, but historical data are often limited. This study leveraged volunteered geographic information and local ecological knowledge from experienced recreational anglers to identify historical baselines and long‐term change in the Rakaia River, a ...

AN ANALYTICAL SOLUTION OF KINEMATIC WAVE EQUATIONS FOR OVERLAND FLOW UNDER GREEN-AMPT INFILTRATION

open access: yesJournal of Agricultural Engineering, 2010
This paper deals with the analytical solution of kinematic wave equations for overland flow occurring in an infiltrating hillslope. The infiltration process is described by the Green-Ampt model.

Incipient subsurface heterogeneity and its effect on overland flow generation – insight from a modeling study of the first experiment at the Biosphere 2 Landscape Evolution Observatory [PDF]

open access: yesHydrology and Earth System Sciences, 2014
Evolution of landscape heterogeneity is controlled by coupled Earth system dynamics, and the resulting process complexity is a major hurdle to cross towards a unified theory of catchment hydrology.

The Application of Autonomous Fixed‐Wing Drones in the Sub‐Antarctic Operating Beyond Visual Line of Sight to Enable Large Area, Multi‐Species Population Monitoring in a Changing Environment

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
Autonomous fixed‐wing drones operating beyond visual line of sight of the pilot were used to conduct the first aerial, multi‐species baseline reference survey at the sub‐Antarctic island of South Georgia. Long‐term population monitoring in this remote, challenging environment has historically proved difficult, with terrestrial monitoring generally ...

Effect of Microtopography, Slope Length and Gradient, and Vegetative Cover on Overland Flow Through Simulation

open access: yes, 2004
Overland flow on a hillslope is significantly influenced by its microtopography, slope length and gradient, and vegetative cover. A 1D kinematic wave model in conjunction with a revised form of the Green-Ampt infiltration equation was employed to ...

Hydrological dynamics and morphological physiognomies of Dzüdza River, Nagaland, India: A Geographical Information System‐based quantification of drainage morphometry

open access: yesRiver, EarlyView.
Abstract The assessment of the morphometric characteristics of the Dzüdza River basin in Nagaland has been critically important for hydrological analysis, flood risk assessment, soil erosion evaluation, and sustainable regional development, owing to its strategic location on the northern fringes of the Himalayas and flanked by hills to the east.

Theoretical framework for updating cross‐sections in river models using non‐standard information coming from crowdsourced images

open access: yesRiver, EarlyView.
Abstract During high rainfall events, one reason for flooding in urban rivers is hydraulic blockages or obstructions in channels. These may cause damming and an immediate increase in upstream water levels, leading to inundation of surroundings. The accuracy of flood models is strongly dependent on the representation of the topography of floodplain and ...

Phasing Out Coal Power Through Cross‐Border Renewable Energy Trade in the Asia‐Pacific

open access: yesSustainable Development, EarlyView.
ABSTRACT Coal remains the backbone of electricity generation in the Asia‐Pacific region, accounting for half of total regional output and two‐thirds of global coal‐fired capacity. The substantial environmental and public‐health externalities of coal highlight the urgent need to accelerate the renewable energy transition.
