Root carbohydrate storage in young saplings of an Amazonian tidal várzea forest before the onset of the wet season Acta Botanica
Scarano,Fabio Rubio; Cattânio,José Henrique; Crawford,Robert M.M..
Root starch and glucose content were measured for young saplings of 18 Amazonian tidal várzea tree species during a dry season. The pattern of carbohydrate storage depended on the type of plant involved and soil topography which is directly linked to flood regime. Most plants showed high root carbohydrate content at this point in the dry season, however, several typically flood-tolerant species (particularly palm trees) presented a low root carbohydrate content, suggesting a strategy of acquiring reserves during the wet season to survive the dry season, when depletion occurs. Plant survival in these flood-prone forests seems to be the result of more than only one adaptive mechanism.

THE FEASIBILITY OF WETLAND RESTORATION TO REDUCE FLOODING IN THE RED RIVER VALLEY: A CASE STUDY OF THE MAPLE RIVER WATERSHED, NORTH DAKOTA AgEcon
Shultz, Steven D.; Leitch, Jay A..
The economic feasibility of alternative wetland restoration activities to store water and reduce flood damage was evaluated in the Maple River Watershed, North Dakota, a sub-watershed of the Red River of the North Watershed. The evaluation was based on recent hydrologic modeling and wetland restoration studies, the National Wetland Inventory, local land rental values, and site-specific historical flood damage. With benefit-cost ratios ranging from 0.08 to 0.13, neither simple wetland restoration based on plugging existing drains, nor restoration with outlet control devices, nor complete restoration intended to provide a full range of wetland-based environmental services were economically feasible over a 20-year future period. Peak flood stages and flood...

THE INFLUENCE OF THE THREAT OF FLOODING ON HOUSING VALUES IN FARGO, NORTH DAKOTA AND MOORHEAD, MINNESOTA AgEcon
Fridgen, Patrick M.; Shultz, Steven D..
The hedonic valuation method (HVM) was used to quantify the impact of the threat of flooding on housing values in Fargo, North Dakota and Moorhead, Minnesota (Fargo-Moorhead). Prices of 3,783 Fargo-Moorhead homes sold between 1995 and 1998 were regressed against structural housing characteristics, neighborhood and environmental indicators, and three flood risk variables. Being located in the 100-year floodplain lowered the sale price of an average home by $8,990 and approximately 81 percent of the price depreciation was associated with required flood insurance premiums. After the extensive 1997 flood, homes in the 100-year floodplain were on average priced $10,241 less than similar homes located outside the floodplain and before the 1997 flood event....

When ENSO Reigns, It Pours: Climate Forecasts in Flood Planning AgEcon
Wernstedt, Kris; Hersh, Robert.
Recent scientific and technical advances have increased the potential use of long-term seasonal climate forecasts for improving water resource management. This paper examines the role that forecasts, in particular those based on the El Nino-Southern Oscillation (ENSO) cycle, can play in flood planning in the Pacific Northwest. While strong evidence of an association between ENSO signals and flooding in the region exists, this association is open to more than one interpretation depending on: a) the metric used to test the strength of the association; b) the definition of critical flood events; c) site-specific features of watersheds; and d) the characteristics of flood management institutions. A better understanding and appreciation of such ambiguities,...

洋桔梗產業發展及栽培健康管理概況 Taiwan Agricultural Research Institute
孫文章; 王瑞章; 江汶錦.
[[abstract]]本計畫針對洋桔梗生育期間遭受淹水後,進行復耕等栽培技術之研究,期能 減少災害損失。埋管排水試驗結果顯示,以埋管排水處理之試區其生育性狀及切 花品質均較以對照區為佳。生育期中摘心保留側芽處理,以保留3 側芽者,其株 高及花苞數表現較佳,保留2 側芽者次之,保留1 側芽者最差。 The purpose of the experiments that are to establish a culture system for recultivation after flooding during of Eustoma. The results shower that the treatment of exclude water by pipe in horticultural characteristics and cut flower qualities were better than check area. The plant heights and Number of flower buds was the best in Keep 3 axillary bud by pinching, followed by 2 axillary bud, 1 axillary bud.
