1.1 Climate change and impacts on hydrological extremes (P.Willems)Stevie Swenne
Presentation of Patrick Willems (KU Leuven) on 'Climate change and impacts on hydrological extremes' during the conference 'Environmental challenges & Climate change opportunities' organised by Flanders Environment Agency (VMM)
Climate change is a significant and lasting change in the statistical distribution of weather patterns over periods ranging from decades to millions of years. It may be a change in average weather conditions, or in the distribution of weather around the average conditions (i.e., more or fewer extreme weather events). Climate change is caused by factors such as biotic processes, variations in solar radiation received by Earth, plate tectonics, and volcanic eruptions. Certain human activities have also been identified as significant causes of recent climate change, often referred to as "global warming"
Scientists actively work to understand past and future climate by using observations and theoretical models. A climate record — extending deep into the Earth's past — has been assembled, and continues to be built up, based on geological evidence from borehole temperature profiles, cores removed from deep accumulations of ice, floral and faunal records, glacial and periglacial processes, stable-isotope and other analyses of sediment layers, and records of past sea levels. More recent data are provided by the instrumental record. General circulation models, based on the physical sciences, are often used in theoretical approaches to match past climate data, make future projections, and link causes and effects in climate change.
Climate change is unbalancing the hydrological cycle in Latin America, causing more extreme floods and droughts. This is shifting hydroelectric power capacity and changing river flows. The Earth Simulator model projects further intensification of rainfall and longer dry periods under climate change. This will compromise the ability of mountain basins to regulate water flows as glaciers recede and fires reduce vegetation. To adapt, impacts must be assessed at the basin level to strengthen systems' resiliency and minimize reliability impacts.
A typicla hydrological report for engineering projects Arkan Hamza Gardi
This document provides an overview of hydrology and the hydrological cycle.

It also provides details on the percentage of the world's water resources that are fresh water versus salt water. The document is a student report submitted to their professor that covers fundamentals of hydrology, examples of hydrological reports, and data analysis.
The document discusses the benefits of exercise for mental health. Regular physical activity can help reduce anxiety and depression and improve mood and cognitive functioning. Exercise causes chemical changes in the brain that may help boost feelings of calmness, happiness and focus.
Description about hydrological cycle, how water lost, condense and replenish on earth. It explains the process of hydrological cycle and factors influencing hydrological cycle.
Climate change is happening as the Earth is warming due to increased greenhouse gas emissions. The average global temperature has risen 0.85°C from 1880 to 2012 and is projected to exceed 2°C by 2100. Small changes in average temperature can lead to large shifts in climate and weather. Evidence shows changes in rainfall patterns, more extreme weather events, rising sea levels, and impacts on ecosystems. The document then provides details on climate change impacts expected for India, such as changes in weather patterns, sea level rise, impacts on agriculture and food security. Case studies on projected climate trends and impacts in Bhubaneswar, India are also presented, along with proposed resilience actions.
The document defines the hydrological cycle as the sequence through which water passes or circulates on and below the earth's surface and in the atmosphere. It discusses the phases of the water cycle, including precipitation, transpiration, condensation, and evaporation. It also notes that human activities like eutrophication can impact the natural water cycle.
The document provides information about the hydrological cycle including key definitions and processes. It explains that precipitation is an input into the cycle, while evaporation and transpiration are outputs. It also describes several transfer processes by which water moves through the cycle, such as surface runoff, infiltration, percolation, groundwater flow, and river discharge.
Recyled aggregates (Concrete Technology and Building Materials)'Animesh Khare'
Recycled aggregates can be used as a substitute for natural aggregates in construction. They are produced from construction and demolition waste and have lower strength but also lower density than natural aggregates. While recycled aggregates provide environmental benefits and reduce costs, their use also faces challenges from a lack of standards and potential for water pollution. Effective recycling techniques include two-stage mixing, mechanical scrubbing, and heated scrubbing to remove adhered cement paste from recycled concrete pieces.
The document discusses global warming and its causes, effects, and potential solutions. It provides background on the greenhouse effect and how increased greenhouse gases are trapping heat in the atmosphere and causing the planet to warm. Some effects that are already occurring include melting ice, rising sea levels, and shifting animal populations and seasons. If warming continues unchecked, impacts could include more extreme weather, water shortages, spread of diseases, and damage to ecosystems. The document explores potential solutions like transitioning to renewable energy sources, improving efficiency, and carbon sequestration to reduce emissions and stabilize the climate. It notes that nuclear power could help lower carbon dioxide emissions by replacing fossil fuel plants but has its own risks to consider.

The California Central Valley Groundwater-Surface Water Simulation Model (C2VSim) simulates the monthly response of the Central Valley’s groundwater and surface water flow system to historical stresses, and can also be used to simulate the response to projected future stresses. C2VSim contains monthly historical stream inflows, surface water diversions, precipitation, land use and crop acreages from October 1921 through September 2009. The model dynamically calculates crop water demands, allocates contributions from precipitation, soil moisture and surface water diversions, and calculates the groundwater pumpage required to meet the remaining demand.
This document discusses using data mining techniques like artificial neural networks (ANN) to model the impacts of nonpoint source pollution in complex coastal estuaries. ANN models can extract relationships from large monitoring datasets to better understand estuary dynamics and the effects of factors like rainfall, tides, and freshwater flows. Case studies of the Cooper River and Beaufort River estuaries show ANN models accurately simulate dissolved oxygen levels and salinity intrusion in response to these drivers. Data mining allows interactive "what if" scenarios to inform total maximum daily load and permitting decisions.

Simulation results show shifts to more sugarcane production and increased profits but limited employment growth under a price increase scenario.
The document discusses hydrological concepts including flow duration curves, meteorological stations, indices used to analyze streamflow, weirs, and the relationship between upstream and downstream areas. It provides definitions and examples of flow duration curves, exceedance probability, flashiness, and how afforestation and cultivation can impact the hydrological response of different biomes. Graphs and diagrams are included to illustrate hydrological responses, streamflow variability, and the impact of land use changes.
Regulating our way to beter creeks and streamsGreg Gearheart
This document discusses challenges with regulating stormwater and hydromodification (alterations to streams) in California. It notes there are many different standards used throughout the state, which vary significantly between regions. Protecting streams requires addressing issues like development, sedimentation, and watershed impacts, but California's regulatory framework is fragmented with different rules for stormwater permits, 401 certifications, and other programs. The document calls for a more unified, technically-based statewide approach to setting hydromodification standards and managing watershed health.
This document summarizes the Lower Susquehanna River Watershed Assessment being conducted to evaluate sediment and nutrient management strategies in the watershed and their impacts on the Chesapeake Bay.

Webinar: Designing a schema for a Data WarehouseFederico Razzoli
Are you new to data warehouses (DWH)? Do you need to check whether your data warehouse follows the best practices for a good design? In both cases, this webinar is for you.
A data warehouse is a central relational database that contains all measurements about a business or an organisation. This data comes from a variety of heterogeneous data sources, which includes databases of any type that back the applications used by the company, data files exported by some applications, or APIs provided by internal or external services.
But designing a data warehouse correctly is a hard task, which requires gathering information about the business processes that need to be analysed in the first place. These processes must be translated into so-called star schemas, which means, denormalised databases where each table represents a dimension or facts.
We will discuss these topics:
- How to gather information about a business;
- Understanding dictionaries and how to identify business entities;
- Dimensions and facts;
- Setting a table granularity;
- Types of facts;
- Types of dimensions;
- Snowflakes and how to avoid them;
- Expanding existing dimensions and facts.
