The past dry summers of 2018, 2019 and 2020 have indicated the sensitivity of Flemish agriculture to drought. In the Flemish polders, this resulted not only in crop water stress, but also in increasing soil and water salinity levels due to the high evaporative demand which rises the historical saline water up to the root zone. Due to the increasing occurrence of weather extremes as a consequence of climate change, farmers and farming systems will need to adapt with both too little and too much freshwater in the future. Compared to conventional drainage systems, controlled drainage can secure crop productivity and lower the irrigation need by draining water only when it is strictly necessary and thereby leaving more opportunities for water retention and groundwater recharge.
As part of the project OP-PEIL, we will investigate the impact of adaptive drainage on water fluxes and availability, water quality as well as on the cropping system itself (crop growth, disease pressure, yield and quality) during 3 years. We will use geophysical techniques to monitor the impact of controlled drainage on the fresh/salt water interface in the drained field, as well as in the nearby landscape. Finally, we will set up numerical experiments using SWAP (water balance model), available historical climate, field management, and soil hydraulic properties data. This numerical experiment aims to evaluate more extensive climatological scenarios. By the end, this project will raise awareness of farmers and stakeholders about the impact of controlled drainage on agricultural practices in the Flemish Polders in Belgium.

This document discusses water management goals and models for two agricultural areas covering 1000 hectares each. It aims for optimal water levels for farming and nature while preventing water issues. The Sobek model simulates a rainstorm over 96 hours, calculating water levels every 5 minutes for 1 month. Questions address water storage capacities in soil and surface water. Calibration requires precipitation data and variances in water levels. Simulations examine summer and winter conditions under different drainage scenarios and capacities. Maintaining infrastructure is important to ensure proper water discharge and storage.

Management and maintenance of water systems involves complying with various regulations at the European, national, provincial and local levels. It requires managing surface waters, beds, embankments, structures, water levels and other components. Key instruments used include the "Legger" which establishes the situation and dimensions, the "Peilbesluit" which sets water levels, and the "Keur" which establishes regulations. Maintenance activities include dredging, mowing, reconstructing side structures and embankments, and removing new growth. Maintenance of structures involves removing dredgings and repairing structures as needed.
The document discusses zoning plans, water assessments, and ledgers related to land development and water management. A zoning plan describes allowed land and building uses, and can regulate details like building heights and distances. Changing a zoning plan's designation requires stakeholder input and can take years. A water assessment analyzes how a zoning change, like converting farmland to urban use, will impact the water system. Ledgers document requirements for waterways regarding location, form, size, and construction, and define management boundaries and protection zones. The case involves stakeholders debating a developer's proposed zoning change, with topics including impacts to the water system and potential problems.
This document discusses different types of weirs used to measure water discharge, including broad crested weirs, thin plate weirs, and Rehbock, Romijn, Cipoletti, circular, and Thomson weirs. Broad crested weirs can be long or short, and influence discharge measurements differently depending on whether water downstream affects flow. Thin plate weirs have a sharp crest and allow measuring the upstream water level where it is streamlined with atmospheric pressure under the nappe. The document also provides a link to a video about a hydrosystem and field trip in Macedonia.
Culverts are civil engineering structures used to allow water to pass under roads or embankments. There are several types of culverts including round concrete tubes, rectangular precast concrete elements, and metal culverts. Culverts require appropriate foundations depending on the material and site conditions, including shallow foundations, foundations on improved soil, or foundations on wooden or concrete poles. Culvert endings can have various shapes like long front walls, receding wings, or return walls to connect to surrounding terrain.
The document discusses various types of pumping stations including Archimedean screws, axial pumps, centrifugal pumps, and submerged pumps. It notes key components of centrifugal pumps like impellers, volutes, and casings. It also covers pump installation methods, switching levels, frequency drives, impeller types for different uses, and hydraulic concepts like duty point and head.
1) Darcy's law describes groundwater flow through porous media according to hydraulic conductivity and hydraulic gradient.
2) Factors that influence groundwater levels include precipitation, soil type, and land use. Heavy rainfall or irrigation can cause groundwater levels to rise.
3) The drainage of an agricultural parcel is calculated based on the hydraulic conductivity, horizontal distance from a stream, and vertical distances between the groundwater level and impenetrable layer and stream level.
This document discusses the hydrological cycle and soil moisture in the unsaturated zone. It describes:
1) The process of rainfall infiltration and groundwater recharge. Water is stored in the pores of the unsaturated zone below the ground surface.
2) Forces that act on soil moisture in the unsaturated zone, including adsorption, osmotic, and capillary forces. Capillary action causes smaller pores to fill with water before larger pores.
3) The soil moisture curve and Staring series, which relate soil type to water pressure and volume of water stored. Finer textured soils like clay can store more water than coarser soils like sand.
Cu07821 3 precipitation and evapotranspirationHenk Massink
1. The hydrological cycle diagram shows the annual water balance for an area, with 800 mm of precipitation, 350 mm of evapotranspiration, 425 mm of surface runoff, and 475 mm of groundwater recharge.
2. Effective precipitation is defined as the volume of precipitation available for groundwater recharge, and is calculated as total precipitation minus actual evapotranspiration, which depends on crop type.
3. Extreme precipitation events like the 1998 "Westlandbui" storm that dropped 100 mm of rain in 24 hours can cause hundreds of millions of euros in flood damage.
This document discusses water management strategies in the Netherlands, specifically focusing on optimal water level agreements. It describes how water levels are managed through water level agreement areas, where the surface water level is fixed and uniform. The typical Dutch strategy involves examining the existing water situation and specifying adjustments to achieve an optimal groundwater and surface water regime. It also discusses how to relate crop selection and production to soil type and groundwater classification using HELP tables. Maintaining appropriate water levels is important for preventing flooding, drying out, and salination while supporting agriculture and nature.
This document provides information about several rural water management courses, including their course codes and names. It then discusses the organization of one course called "Rural Water Management" including that it has both theory and assignment classes each week. The document outlines the course assignment which is to prepare a water level agreement for a polder in Noord Beveland. It also lists the criteria for marks in the course. The rest of the document covers hydrological cycle concepts and diagrams, reasons for managing water systems, how water systems can be adjusted, key topics covered in the course, and an exercise on simple water level areas.

This document provides a summary of research projects conducted by the Delta Academy Applied Research Centre between September 2014 and January 2015. The research was divided among four main research groups: Aquaculture in Delta Areas, Building with Nature, Water Technology, and Water Safety & Area Development. The projects covered a wide range of topics including algae cultivation, shellfish feeding, bioremediation, coastal ecosystem restoration, wastewater reuse, community resilience, and water management in the Dutch delta region.
The dimensions of the culvert are calculated to be 3 m x 2 m based on trying different cross-sectional areas. The total head loss is calculated using the given discharge of 3 m3/s, upstream velocity of 1 m/s, and downstream velocity of 0.5 m/s. A cross-section of 3 m x 2 m results in a head loss of 0.45 m, which is less than the maximum allowed head rise of 0.5 m. Sketches are provided showing the elevation of the total head and pressure lines.

FEEDING TRIALS OYSTERS
The quality of algal biomass as feed for shellfish is dependent on the cultivation parameters. In order to
determine the effect of algal quality on shellfish growth and condition, feeding trials with oysters using
algae cultivated under different parameters are needed. In cooperation with the algae research a set of
feeding trials will be designed and executed. Growth and condition parameters of the oysters will be
determined. This will give insight in the effect of algal quality on shellfish production parameters.
