Yağmur Suyu Hasadı ile Peyzaj Bitkilerinin Su Tüketimi Arasındaki İlişkinin Değerlendirilmesi

Öz

Yağmur suyu değerlendirilmediği sürece atık olarak görülmekte ve yüzey suyu olarak yeraltı kaynaklarına veya denizlere ulaşmaktadır. Azalan su kaynakları düşünüldüğünde, yağmur suyu sadece yüzey akış suyu olmamalı, yeniden kullanımı ile yeraltı ve şebeke sularından tasarruf sağlanmalıdır. Su tüketim oranlarına baktığımızda, peyzaj alanlarının sulanması için büyük miktarda suyun kullanıldığı tartışmasız bir şekilde görülmektedir. Ayrıca bitkilerin su ihtiyacı bilinmemekte ve bilinçsiz sulama ile su israf edilmektedir. Bu çalışmada yağmur suyunun yeniden kullanımı ile su döngüsüne katkı sağlanması amaçlanmıştır. Aynı zamanda bitkilerin türlerine göre su isteklerini ortaya koyarak, doğru miktarda sulama yapılmasını hedeflemektedir. Bu iki temel hedef suyun etkin kullanımını sağlarken, bitkilerin isteklerini öğrenmeyi amaç edinmiştir. Çalışma alanı içerisinde farklı malzemelerden toplanacak yağmur suyu miktarı Rasyonel Method, her bir bitkiye ait su tüketim hesabı CropWat 8.0 programı ile hesaplanmıştır. Sonuç bölümünde, toplanacak yağmur suyu miktarı 494.000 m3 yıl, bitkilerin sulama suyu ihtiyacı 54,530 m3 yıl olarak hesaplanmıştır. Bu veriler, toplanan yağmur suyu miktarının bitkilerin sulama suyu ihtiyacını karşıladığını göstermektedir. Yerleşke içerisinde toplanacak yağmur suları tanklara yönlendirilmektedir. Tank hacimleri hesaplanmıştır. Depolanan yağmur suları dışında arta kalan yağmur suları için sürdürülebilir yöntemler ile yerinde çözüm önerileri üretilmiştir.

Evaluation of the Relationship Between Rainwater Harvesting and Landscape Plant Water Consumption

Öz

If rainwater is not used, it is considered waste and ends up as surface water in underground resources or flows into oceans. In view of dwindling water resources, rainwater should not only flow as surface water but should be reused to conserve groundwater and mains water. To achieve this, rainwater must be collected and solutions produced on site. When we look at water consumption rates, we realize that a large amount of water is significantly used for the irrigation of landscaped areas. In addition, the water requirements of plants are often not known and water is wasted through unconscious irrigation. This study aims to provide the right amount of irrigation by showing the water requirements of plants according to their species. At the same time, it aims to provide the right amount of irrigation by showing the water requirements of plants according to their species. These two main objectives are aimed at learn the needs of plants and at the same time ensuring efficient water use. In this study, it is aimed to contribute to the water cycle by reusing rainwater. Various roofing and paving materials were identified in the study area. The amount of rainwater to be collected from the different materials within the study area was calculated using the Rational Method and the water consumption of each plant was calculated using the CropWat 8.0 program. In conclusion, the amount of rainwater collected on the entire campus was calculated as 494,000 m3per year and the amount of irrigation water required by the plants was 54,530 m3per year. This data shows that the amount of rainwater collected corresponds to the water consumption of the landscape plants. The rainwater harvested on campus is fed into tanks. The rainwater collected on the campus is channelled into tanks. The volume of the tanks was calculated. In addition to the stored rainwater, solutions were developed on-site using sustainable methods for the remaining rainwater. Plants with low or medium water requirements are recommended for use in new landscape areas.
