    the Fraser Valley alone for agriculture – and almost all of it can be irrigated. Another revealing comparison - ~20, ha of irrigated area in the Okanagan Valley versus ~13, ha just within the Metro Vancouver regional district. Sea Level Rise and the Impacts to our Infrastructure in the Lower Fraser John ter Borg, University of British. a spatial resolution of by , we present the first global analysis of the impact of climate change and climate variability on irrigation water requirements. We compute how long-term average irrigation requirements might change under the climatic conditions of the s and the s, as.

    The earliest archeological evidence of irrigation in farming dates to about B.C. in the Middle East's Jordan Valley (1). It is widely believed that irrigation was being practiced in Egypt at about the same time (6), and the earliest pictorial representation of irrigation is from Egypt around B.C. (1). In the following millennia. The actual irrigation design group assesses the information, specifies the precise crop water demands, does hydraulic computations in order to determine the pieces and structure of your irrigation system, the water pressure which will likely be utilized all through the irrigation system, as well as the irrigation .

    Increased groundwater recharge stems from the unavoidable deep percolation losses occurring in the irrigation scheme. The lower the irrigation efficiency, the higher the losses. Although fairly high irrigation efficiencies of 70% or more (i.e. losses of 30% or less) can occur with sophisticated techniques like sprinkler irrigation and drip irrigation, or by well managed surface irrigation, in. methodology to reduce the annual water requirements for crops irrigated with a drip/trickle system. Table lists the historical peak evapotranspiration (ET) rates for locations in B.C. using an average maximum soil water deficit (MSWD) of 3-inch or cm. The irrigation system flow rate requirement can be estimated using the peak ET.

Hardy, irrigation engineer. and climatic factors which are closely related to climatic demands. Irrigation requirements are primarily determined by crop water requirements, but also depend on the char-acteristics of the irrigation system, management practices, and the soil characteristics in the irrigated area.

Best Management Practices (BMP) for IrrigationFile Size: KB. This paper presents a simple approach for estimating the spatial and temporal variability of seasonal net irrigation water requirement (IWR) at the catchment scale, based on gridded land use, soil and daily weather data at × m resolution.

In this approach, IWR is expressed as a bounded, linear function of the atmospheric water budget, whereby the latter is defined as the difference Cited by: 9. Locate and compare Irrigation Systems & Equipment in Upper Fraser Valley BC, Yellow Pages Local Listings.

Fleming and Quilty () used climatological composite analysis to investigate ENSO signals in long-term shallow groundwater level observations from four wells in the lower Fraser Valley of.

The Okanagan has more than 85% of all fruit producing areas in B.C. and almost all fruit is irrigated (20% of B.C.;irrigated area). In contrast, the Lower Fraser Valley has more than 80% of the berry, green houses and vegetable producing areas in B.C. and about 90% of the provincial dairy and poultry production is located in the Lower Fraser.

Subsurface drainage and sub irrigation were simulated in the Lower Fraser Valley of British Columbia under different water regimes with DRAINMOD and the results were compared with data obtained from conventional subsurface drainage and subirrigation field experiment at Boundary Bay in the Lower Fraser Valley.

Predicted and measured water table depth were compared for 4 years (. Climatic data observed at six meteorological recording stations in the south central Interior of British Columbia were used to analyse the temporal and geographical variations in the frequency, intensity and duration of various climatic phenomena that affect the supply and demand of water by growing crops.

Rather than using average values, the relative frequencies of occurrence of each element. The use of the Land Suitability Rating System to assess climate change impacts on corn production in the lower Fraser Valley, British Columbia Article in Canadian Journal of Soil Science 96(2.

The crop water requirements of plants, and therefore irrigation requirements, would also increase should warmer climatic conditions manifest themselves.

A study in assesses the potential effects of global climate change in South Africa, Lesotho and Swaziland.

In the study, 1 60% of the world average. The last deglaciation cycle in the lower reaches of the Fraser River, also called the Lower Mainland, began by ≥12, 14 C yr B.P. The major remaining ice flow was fed by numerous valley glaciers and occupied the Fraser lowlands, with the glacial margin likely ending at about what now are Aldergrove and Fort Langley (Fig.

INCA calculates crop water requirements at 'field' level on the basis of reported cropping activity and monitored climatological conditions.

Field requirements are routed through the irrigation network according to operational rules specified by the system management.

The soils within the Fraser Valley are some of the most fertile in Canada However, urban and residential development has occurred on, and in close proximity to, these prime agricultural lands.

The majority of agricultural land is located along the broad floodplain of the Lower Fraser. A certain crop grown in a sunny and hot climate needs more water per day than the same crop grown in a cloudy and cooler climate. There are, however, apart from sunshine and temperature, other climatic factors which influence the crop water need.

These factors are humidity and wind. University Sprinklers is actively installing and servicing irrigation systems in Abbotsford, Mission and Chilliwack, and has a great reputation amongst home owners, builders, property managers and businesses in the Fraser Valley.

While attention has, appropriately, been focused on getting food and medicines to the victims of the famine in the Horn of Africa, many observers are asking about longer-term solutions, especially if droughts such as the current one become more frequent with climate change.

One possibility is to expand irrigation. Currently.
