A network-indexbased version of TOPMODEL for use with high-resolution digital topographic data [PDF]

, 2004
This paper describes the preliminary development of a network index approach to modify and to extend the classic TOPMODEL. Application of the basic Beven and Kirkby (1979) form of TOPMODEL to high resolution (2.0 m) laser altimetric data (based upon the ...

How cold is too cold? A theoretical analysis of the optimal trigger for index insurance for frost damage to crops

American Journal of Agricultural Economics, EarlyView.
Abstract Crop insurance is undoubtedly an extremely valuable element in protecting agricultural businesses, but in many cases standard indemnity‐based products have had very low uptake due to high transaction costs elevating premiums to unaffordable levels.

Exploring the ability of LSTM-based hydrological models to simulate streamflow time series for flood frequency analysis [PDF]

Hydrology and Earth System Sciences
An increasing number of studies have shown the prowess of long short-term memory (LSTM) networks for hydrological modelling and forecasting. One drawback of these methods is the requirement for large amounts of training data to properly reproduce ...

Optimizing bio-retention system locations for stormwater management using genetic algorithm [PDF]

, 2014
As part of stormwater best management practices, bio-retention systems have been applied in a number of developed countries to minimize the change of hydrological regime due to urbanization. Optimization techniques have also been applied to determine the

Response of hydrological processes to input data in high alpine catchment : an assessment of the Yarkant River basin in China [PDF]

, 2016
Most studies of input data used in hydrological models have focused on flow; however, point discharge data negligibly reflect deviations in spatial input data.

Seeds of change: The impact of Ethiopia's direct seed marketing approach on smallholders' seed purchases and productivity

American Journal of Agricultural Economics, EarlyView.
Abstract While multiple factors explain low adoption rates of improved varieties by small‐scale farmers in sub‐Saharan Africa, a key supply‐side constraint is the limited availability of seed embodying new traits in the volume, quality, price, and timeliness required by farmers. This constraint is partly attributable to classical failures in the market

Evaluation of the effects of underlying surface change on catchment hydrological response using the HEC-HMS model [PDF]

Proceedings of the International Association of Hydrological Sciences, 2014
Due to rapid population growth, China, and urbanization, the Dongwan catchment, with a drainage area of 2856 km2 and located in Henan Province, has been subjected to considerable land-use changes since the 1990s.

Accounting for animal health in efficiency analysis: An application to Swedish dairy farms

American Journal of Agricultural Economics, EarlyView.
Abstract Poor animal health is a central concern in modern livestock production. Despite the necessity to incorporate animal health in efficiency analysis, the theoretical and empirical developments are limited on this subject. This article appropriately characterizes the axiomatic properties of animal health within a production framework.

Comparing hourly climate change projections for hydrology in a Mediterranean meso-scale catchment

Journal of Hydrology: Regional Studies
Study Region: The 42km2 Claduègne catchment in southern France, under Mediterranean climate is subject to long, dry summers with limited water resources and intense, convective storm events leading to flash floods and overland flow (OF). Study Focus: The

Sediment transport modelling in a distributed physically based hydrological catchment model [PDF]

Hydrology and Earth System Sciences, 2011
Bedload sediment transport and erosion processes in channels are important components of water induced natural hazards in alpine environments. A raster based distributed hydrological model, TOPKAPI, has been further developed to support continuous ...
